This invention relates to a multiple map holder and more particularly toa holder in the form of a roller shade or curtain with which'a pluralityof maps, charts or display sheets or curtains are adapted to beassociated with a main curtain 0r 'apronin such a way that any selectedmap or chart may be conveniently displayed by simply pulling down on alabeled'pull strap whereby the maps behind the selected map are adaptedto move downwardly with the selected map, while the maps in front of theselected map are adapted to unroll behind the roller and hang in alooped position within the apron forming a 1 part ofthe device.

It is an obj ect'of this invention to provide a multiple map holderwherein a roller has a main curtain or apron secured thereto in additionto a plurality of superimposed maps or charts in such a way that thevarious mapsor charts may be selectively displayed while the maincurtain or apron is supported to assume a looped position when thecurtain is unrolled while the maps in front of a selected map areadapted to have the ends thereof supported in stationary brackets,permitting the maps to assume looped positions within the apron whilethe maps behind" the selected map are adapted to be loweredsimultaneously with the selected map. 1

It is a further object of this invention to provide a multiple type mapholder-provided with a curtain or main shade and a plurality of maps orcharts which are adapted tovbe selectively. displayed by merely pullingclownwardly on a ring carrying labeled strap, one ofwhich is attached toeach of the maps.

It is furthermore an object of this invention to provide a roller typemultiple map 40 holder wherein a plurality of maps are supported on aroller which is adapted to be operated by pulling downwardly on any oneof a plurality of labeled straps connected with the maps, said labeledstraps adapted to normally hang in front of the roller device in areadily accessible position and are furthermore adapted to be heldinsaid accessible position by means of a retaining or st'opmemberpivotally supported on the bracket on which the multiple map holder isengaged,

Another object of the invention is to provide a multiple type map holderwherein the labeled ring carrying straps connected to the respectivemaps or charts forming the device are adapted to hang in a readilyaccessible position and are prevented from swinging out of said positionby means of a retaining member supported above the map roller which alsoserves as a dust guard to prevent dust from collectingbetween the endsof the various charts when the device is in its normal or rolled upposition.

Still another object of this invention is to provide a roller typemultiple map holder wherein a guard apron and a plurality of charts aresecured on a roller in such a way that a brace rod in the end of theapron is adapted to be supported on a stationary support so that theapron will assume a looped position for receiving looped portions of aselected number of charts, while the remaining charts are adapted to belowered with a selected chart which, when lowered, assumes a convexposition or shape permittingthe subject matter of the selected chart tobe readily read or viewed without distortion.

It is another object of the invention to provide a roller type ofmultiple map holder embracing a roller carrying a main curtain or apron,and a plurality of charts in a predetermined relation with each of saidcharts having a labeled ring carrying strap attached thereto andsuspended over the roller when the apron and maps are rolled up so thatany one of the charts may be selectively engaged and pulled downwardly,said apron assuming a looped position to receive a plurality of thecharts while the remaining charts, namely those behind the selectedchart, are adapted to be lowered in unison with said selected chart.

It is an important object of this invention to provide an improvedroller type multiple chart display device of simplified and improvedconstruction whereby a plurality of charts of the roller shade type areassociated with a roller shade apron in such a way that the apron willact as a protecting device for the charts when the same are rolled upand will furthermore assume looped position and act as a pocket forreceiving certain of the charts when the remaining charts aresimultaneously lowered for the purpose of dis-' playing a selected chartmadepossible by merely engaging and pulling down on the labeled strap ofthe selected chart, which strap is normally. positioned in a readilyaccessible positionsuspended infront of the rolled up apron and chartsbeneath a pivoted retaining member, provided for the purpose ofpreventing the labeled-straps from swinging into. inaccessiblepositions.

Other and further important objects of'this invention will'be apparentfrom the disclosures in the specification and theaccompany ing drawings.V I

This invention (in a preferred form) is illustratedinthe drawings andhereinafter morefully described, 1

On the drawings Figure 1 is a front elevation of an im-' proved multipletype map holder embodying the principles of this invention with aselected chart lowered half way in front of the looped curtain apron andbehind thehang;

' ing straps connected with the respective re-' maining charts whichunwind with the curtain apron and are disposed Within saidcurtain apronbeneath'a pivoted dust guard and retaining member which actsto retainthe straps in an accessible position. 1

Figure 2;is an enlarged end elevation of the multiple map holder withthe curtain apron and the charts completely rolled up and disposedbeneath the combination dust guard-and strap, retaining device. Figure 3is'a similar end view of the multiple map holder showing a selectedchart partially lowered and also'illust'rating the remainingcharts inlooped position within the guard apron.

As shown onthe drawings:

The reference numeral 1 indicates a wall or other suitable support,having removably or rigidly engaged thereon a mounting board or barQhavmg secured thereon in spaced relation roller supporting brackets 3and 4, which may be of any standard type for-re- 'movably receiving andsupporting-a curtain roller 5 in horizontal position. The bracket arms 3and etproject upwardly and outward I ly in an inclined position from thesupporting boarcl 2to afford upper inclined edges 6.

Integrally formed on each of'the'brackets 3 and 4 is an upwardlydirected plate or arm 7, the upperend of which is twisted or formed tobepositioned at'right angles with respect to the mounting board-2 toform a bracket plate 8 which is provided with a' notch 9 in the upperend thereof. 1 7

Attached to the standard curtain roller 5 is one end margin of a maincurtain or apron w 10, the other end margln of which is provided with. ahem through which areinforcingor stiffening rod 11 .is engaged, The endsof the stiffening rod 11 project beyond the sides of the apron 10 adistance sufficient to permit the ends of the rod to be removablyengaged in the notches'9 of the bracket plates 8'as illustratedinFigures 2 ancl'3of the drawings. The curtain or apron 10 is adapted tobe rolled up on thespring roller 5 in the customary manner. I Inthepresent instance, however, the outer end of the apron 10 is adapted tobe normally'supportedin an elevated position by placing the reinforcingor stiffening rod 11 with the ends thereof seated, in the notches 9 ofthe bracket plates 8.

Secured in superimposed relation'with respect to one another upon thefrontsurface of the curtain or apron 10 are-a plurality of maps, chartsor the like designated by the reference numeral 12. The upper endmargins of the respective maps or charts are seated in superimposedrelation and may be s'e cured either to the outer face ofthe apron 10 ordirectly to the spring roller 5, as desired.

The other end marginsof the charts 12 are bent over and formed toprovide hems 13. Rigidly secured in eachof the chart hems 13 is astiffening rod 14, the'ends of which project beyond the side margins ofthe chartsso that when the apron and the charts are completely'rolled upon the roller 5, the ends of the chartrods 14; will be positioned to therear of the roller and above the bracket-arms 3 and 4 and above thesupported end of the curtain apron 10 as illustrated in Figure. 2. Thechart rods 14 are of sufficient length to permit the ends, thereof toproject beyond the brackets-.8 and 4.- Attached to the hem or rod of'eachof the maps or charts 12 isapull v strap 15having a ring 16 engagedin the outer end thereof. As illustrated in Figure 1, the

pull straps 15 on the various charts are positioned at space intervalsacross the front I of the map holder and are normally adapted to hangdownwardly infront of the rolled up maps or charts-to position the rings16 so V .and comprises a- U-shapedorchannel shaped frame 17 the ends ofthe sidearms ofiwhich are bent at right angles and are pivot-allyengaged in screw eyes orj-sup'porting members .18, fastened in thetopof, the mounting bar 2 as illustrated-in Figures2 and 3. The pivotedframe 17 is provided with a covering to afford a dustig ua-rd' orcover-over'the top of the. map holder to prevent dirt and the like fromentering between-the ends'of the charts when1tlie same are in rolledup'position. As illustrated in Figures, 2 and 3, the dust guard andframe 17 are normally adapted to be swung forwardly in an inclinedpositionwith the front portion of the frame resting upon the rolled upcharts and upon the pull straps 15 to hold said straps in an accessibleposition. The arms of" the guard frame 17 when in the positionillustrated in Figures 2 and 3, also serve as ameans for retaining theapron rod 11 seated in the notches 9 of the bracket plates 8.

" The operation is as follows:

I A multiple map holder or chart of the class described is adapted tohave the roller 5 thereof supported in the ends of the brackets 3 and 4which are in turn mounted in any suitable position upon a supporting bar2 or on a wall of a room in which the improved multiple map holder is tobe used. When the multiple map roller is mounted in position, the guardframe 17 is pivotally swung upwardly in an out-of-the-way po sition andthe hem end of the curtain or ported end of the apron 10, as illustratedin Figure 2 to permit the projecting end of the stiffening rods 14 ofthe charts to project beyond the ends of the inclined edges 6 of theroller supporting brackets 3 and 4. The

pull straps 15 for the various maps or charts pass beneath the pivotedretaining frame 17 and hang in front of the rolled up maps, asillustrated in Figure 1 to permit any desired map or chart to bedisplayed. The straps 15 may be labeled to identify the various maps orcharts to make it convenient to i use the multiple map holder. When itis desired to display a particular chart, a person has merely to selectthe proper pull strap 15 and pull downwardly on the same, therebycausing the roller to revolve to unroll the selected map together withthe other maps positioned behind the same. The maps or charts which arepositioned in front or over the selected chart unwind from the rollerand loop in the curtain or apron 10, while the pull straps for saidcharts remain in their normal position projecting from beneath theretaining frame 17.

When the multiple map holder is operated, the rods 14 of the maps orcharts in front of a selected map or chart are permitted to slidedownwardly over the inclined edges 6 of the roller supporting brackets 3and 4, as illustrated in Figure 3. Vhen the multiplemap holder isoperated to display a selected map or chart, the curtain or apron 10,having one end thereof supported on the reinforcing rod 11 engaged inthe bracket around the roller, any one ofthe pull straps of theloweredmaps may be pulled to release the roller, permitting the roller torotate to wind up the maps or charts into their normal position with therods 14 of the charts positioned above the brackets 3 and 4 and with thepull straps hanging in front of the rolled up maps and beneath the guardframe 17 Attention is called to the fact that when a selected map'ispulled down or displayed, that the roller rotates forwardly, therebycausing the selected chart to assume a slightly convex shape resultingfrom the rolled up condition of the chart. The convex surface of thechart permits the map reading matter or pictures contained on the chartto be readily read or viewed without distortion, which is a decidedadvantage over the old type of multiple maps, wherein the selectedcharts or maps, when displayed, assume a concave position. By having theends of the various maps or charts provided with the projecting rods,which are disposed normally above the brackets 3 and 4, the device canbe easily operated and affords an arrangement wherein the various chartsor maps always assume or are returned to the same relative Positions,thereby always maintaining the tension in the roller spring andobviating rewinding of the roller spring.

The improved multiple type map holder may be used for geographical maps,charts, tarifl? sheets and the like, and may be mounted in position highupon a wall or on a lower support, since the improved arrangement of thering carrying pullstraps is such that a hooked pole or rod may be usedto engage any of the rings of the maps when the holder is mounted highon a wall to permit any selected map or chart to be. convenientlydisplayed. In case the holder is mounted in a low position, an operatormay personally select and engage the pull strap of any desired map toproperly display the same.

The improved pivoted frame or shield 17 is provided to prevent the pullstraps from swinging upwardly in back of the roller in an out-of-the-wayposition in case the roller is accidentally released and rolls up toorapidly.

While the main curtain or apron as illustrated and described inconnection with the improved multiple mapholder is provided to afford adust shield for the maps or charts,

and also provides means for relieving, the V3,, .rious map rods fromstresses or strains in the operation of the device, it will, of course,be understood that the main curtain or apron '15 appendediclaimsr Imaybe omitted Without, in any Way, changin g the operation of themultiple display map device. 1 When the main-curtain or apron. isomitted,- the rods engaged inthe hems of the various maps orrcharts areadapted to serve as .a means forsu'pporting the charts which maybeloopedbehind the certain-selected map on' display:
